COOLING ATTACHME F MbTOBiIDRWEN F I To all whom it'mag concern.-

'Be'it known that-L-VVILBUR A. Gnovnn, a citizen of the United States,residing at Long Lake, in the State of Washington, have inve'ntedcertain new and useful Improvements in Cooling Attachments-for Motor-Driven Fans; and I do' hereby declare the following to be a full;clear, and exact description of the invention, such as will means for vsupplying moisture v continuously moisture to and receive-moisture from[thefabric,-'su"ch frame to be inverted to reverse thejdirection of flowofthefluid'.

The present invention is adapted to be associated' with motor drivenfans of; any ordinary or approved build, aeonventional elec tric fanmotor being shown iat lO in Fig. 1 j' with the invention attachedthereto.

The invention comprises; a frame. 1 1

mounted upon the motor 10 so as to-"be'rotat-ed to reverse by employingany approved means as the movable collar 12.

.l/Vhen' the fluid has all flowed from the I upper receptacle across tothelower receptaclethe frame is'inverted by simply rotating upon-themeans attaching to the motor, as for inst'anceithe' collar 12, whichreverses the flow of the fluid so that thereceptacle previously locatedat the bottom' now becomes the top reservoir and the fluid fl therefromagain across'the'screen or fabric" 13 to the lower'reservoir. It willthus be seenthat the fluid is used continuously until evaporated simplyreversing .theframe as often as may be'necessary and that when the fluidhas been evaporated 'it is replen- I ished by refilling one or both. ofthe [reservoirs by removing-.the 'serew' cap 16; Y
